Building snap-core

Building the Haddock Documentation

The haddock documentation can be built using the supplied haddock.sh shell
script:

./haddock.sh

The docs get put in dist/doc/html/.

Building the testsuite

Snap is still in its very early stages, so most of the "action" (and a big
chunk of the code) right now is centred on the test suite. Snap aims for 100%
test coverage, and we're trying hard to stick to that.
